Given numbers are 686, 133, 928, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 133) = 13034
GCD(686, 133) = ( 686 x 133 ) / 13034
= 686 / 133
= 686
Step2:
LCM(7, 928) = 6496
GCD(7, 928) = ( 7 x 928 ) / 6496
= 7 / 928
= 7
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 686, 133, 928, 257 is 1
